The CAS Registry Mumber 90282-39-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,8 and 2 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 90282-39: (7*9)+(6*0)+(5*2)+(4*8)+(3*2)+(2*3)+(1*9)=126 126 % 10 = 6 So 90282-39-6 is a valid CAS Registry Number.
